Abstract: An anti-theft system for securing a removable battery to a power tool. The system employs a tamper-proof retainer to ensure that the retail display of a combined power tool and its associated battery can be displayed as a single unit without fear of theft of the battery. This may be achieved by the tamper-proof retainer securing a battery release latch against its release position hence securing the battery to the tool in a manner preventing the removal of the battery by a potential thief. The tamper-proof retainer either prevents removal of the battery from the power tool, as removal of the tamper-proof retainer is impossible, or, if it is destroyed by a thief, then it permanently secures the battery to the power tool.

Abstract: A battery pack with a housing, at least one battery cell contained within the housing, a first terminal and a second terminal. The housing includes a substantially ovoidal surface which is substantially symmetric about a first axis of symmetry and a second axis of symmetry which is transverse to the first axis. The surface has first and second substantially linear terminal openings. The first opening extends substantially parallel to and is non-coincident with the first axis, while the second opening extends substantially parallel to the second axis. The first and second terminals are disposed within the housing adjacent to the surface. The first terminal is accessible through first opening and the second terminal is accessible through the second opening. A device for using the battery pack is also provided.

Abstract: A key pad (6) is provided for the on/off switch for a powered hand tool (2) in which the on/off switch is of the rocker type in which the switch mechanism is actuated by a rocker member (16) comprising two rocker components (18,20) pivoted about a pivot point (22) and is switched by applying pressure selectively to one of the two rocker components (18,20). The key pad (6) forms a sealed cover for the rocker switch (16) and is moulded from a resilient material, and comprises a pair of actuator pads (8,10), each of which actuator pads (8,10) is associated with a corresponding rocker component (18,20) of the rocker switch (16) and is moulded as a relatively thick pad section (8,10) linked to the key pad wall (12) by a relatively thin deformable circumferential linking section (14) and can be selectively switched between a first stable position and a second stable position in which the actuator pad (8,10) is depressed relative to the first stable position.
